Effects of CB on the expression levels of claudin-1, claudin-2, occludin and ZO-1. (A) Protein expression levels of claudin-1, claudin-2, occludin and ZO-1 in each group were measured using western blot analysis. (B) mRNA expression levels of claudin-1, claudin-2, occludin and ZO-1 were determined using reverse transcription-quantitative PCR. Data are presented as the mean ± SD. ^*P<0.05 vs. control group; ^#P<0.05 vs. DSS group. ZO-1, zona occludens protein 1; CB, Clostridium butyricum; DSS, dextran sodium sulfate.
